DETAILED DESCRIPTION

FIG. 1 is a block diagram of a system 100 for automatically creating amedia archive from content stored on a recording medium 103. In oneembodiment, a user is not required to explicitly instruct the system 100to create the media archive other than to initiate playback of thecontent (or to simply insert the recording medium). Subsequently, theuser may view the media content directly from a media archive withouthaving to use the recording medium.

In one embodiment, the system 100 includes a media player 101. The mediaplayer 101 may include a media reader 102 capable of reading mediacontent (e.g., movies, television shows, audio recordings, games, etc.)from a recording medium 103, examples of which may include digitalversatile discs (DVDs), Blu-Ray® discs, compact discs (CDs), solid-statememory devices, Flash memory devices, or the like. The media player 101may also include a user interface component 104, an archival component105, a media playback component 106, a media analysis component 107, atranscoder 108, a decoder 109, a metadata component 110, and acommunication module 111. The media player 101 may further include acomputer-readable storage medium 112, which may include one or morearchived media content items (e.g., content items 113A and 113B). Eachof the components 104-112 is described in greater detail below.

The components 104, 105, 106, 107, 108, 109, and/or 110 may beimplemented as computer-readable instructions executable by a generalpurpose processor, such as a Core™ 2 Duo processor from Intel®, anAthlon™ processor from Advanced Micro Devices (AMD), or the like, and/ora special purpose processor, such as an Application Specific IntegratedCircuit (ASIC), a Field Programmable Gate Array (FPGA), or the like. Insome embodiments, the components 104, 105, 106, 107, 108, 109, and/or110 may be implemented using a combination of processors, such as ageneral purpose and a special purpose processor. Similarly, one or moreof the components 104, 105, 106, 107, 108, 109, and/or 110 may includededicated hardware components. For example, the decoder 109 may includedecoder hardware controlled by instructions executing on a generalpurpose processor.

The media player 101 may be coupled to a display 120, such as atelevision, computer monitor, a PDA/smart phone display, etc., using oneor more standard video connections, e.g., High-Definition MediaInterface (HDMI), Radio Frequency (RF) coaxial, composite video,S-video, Digital Visual Interface (DVI), Video Graphics Array (VGA), orthe like. The display 120 may present media content to a user 122, whomay control the operation of the display 120 and/or media player 101using a remote control 124. Alternatively, or in addition, the mediaplayer 101 may be communicatively coupled to a remote display 124 via anetwork 130. In such an embodiment, the media player 101 may beconfigured to stream media content to the remote display 124 over thenetwork 130.

The media player 101 may include one or more inputs (not shown) to allowthe user 122 to control the operation of the media player 101.Alternatively, or in addition, the user 122 may control the operation ofthe media player 101 using a remote control device 123. The userinterface component 104 of the media player 101 may present controls,status information, and other interface components on the display 120and/or the remote display 124. The user 122 may interact with the userinterface presented by the user interface component 104 to view thestatus of the media player 101 and/or control its operation.

As will be described in additional detail below, an archival component105 of the media player 101 may be configured to archive at least aportion of the media content on the recording medium 130 on thecomputer-readable storage medium 112. FIG. 1 shows examples of archivedcontent items 113A and 113B.

In one embodiment, the media content on the recording medium 103 may beconcurrently archived by the archival component 105 and played back bythe playback component 106 e.g., in a single “play and save” operation.As such, the user interface component 104 may provide a “play and save”user interface input element. Selection of the play and save input by auser 122 may cause the archival component 105 to begin archiving andplaying the media content on the recording medium 103.

Alternatively, or in addition, the archival may commence as soon as therecording medium 103 is made available to the media player 101. Forexample, the archival component 105 may begin archiving a recordingmedium 103 as soon as the medium 103, such as a DVD disc, is insertedinto the media reader 102.

As shown in FIG. 1, the storage medium 112 may store one or morearchived media content items (e.g., content items 113A-113B). Thestorage medium 112 may include, but is not limited to one or more harddiscs (e.g., discs comprising magnetic storage medium), optical media,volatile memory, non-volatile memory, Flash memory, or the like. In someembodiments, portions of the storage medium 112 may be disposed withinthe media player 101 and other portions of the storage medium 112 may bedisposed externally of the media player 101. The portions of the storagemedium 112 disposed outside of the media player 101 may becommunicatively coupled to the media player 101 via a Universal SerialBus (USB) connection, an IEEE 1394 (Firewire®) connection, a networkconnection, or the like. In some embodiments, the storage medium 112 mayinclude a plurality of storage devices, such as a Redundant Array ofInexpensive Discs (RAID), a storage area network (SAN), anetwork-attached storage (NAS), a cluster, or other data storageconfiguration. Similarly, portions of the storage medium 112 may beremovable from the media player 101. For example, discs may be swappedinto and out of the media player 101, flash or other memory types may beinserted and/or removed from the media player 101, and so on.

After the multimedia content on the recording medium 103 is archived inthe storage medium 112 (e.g., content items 113A and 113B), the contentmay be played by the playback component 106 of the media player 101without requiring the recording medium 103 to be inserted into theplayer 101. Similarly, the playback component 106 may play media contentfrom the storage medium 112 as it is archived by the archival component105 (e.g., concurrently with archiving the media content 103).Collectively, the stored content items 113A and 113B are referred toherein as a content “archive” or “library.”

As an example, a user may have a DVD movie collection including dozensor even hundreds of DVDs. As each DVD movie is played in the mediaplayer 101, a backup or archive of the movie may be stored on thestorage medium 112. Archival may take place upon insertion of therecording medium 103 into the media reader 102 or in response to asingle command to play and save the recording medium 103 received viathe user interface component 104 (e.g., via a “play and save” userinterface element). Once the contents of the DVDs have been added to themedia archive, subsequent playback using the playback component 106 mayoccur without having to handle the recording medium 103. In this way, amedia archive may be automatically created as one or more users of themedia player 101 play various recording media (e.g., such as therecording medium 103), without requiring the one or more users toperform a dedicated archiving step.

In some embodiments, the media analysis component 107 of the mediaplayer 101 may be configured to analyze the recording medium 103 as therecording medium 103 is archived in the storage medium 112. The mediaanalysis component 107 may allow the media player 101 to determine thestructure of the media on the recording medium 103. For example, a DVDmovie stored on the recording medium 103 (e.g., a DVD movie disc) mayinclude various segments, such as one or more previews, one or morespecial features, one or more menus, the movie itself (e.g., comprisingone or more “chapters”), and so on. The media analysis component 107 mayidentify each segment on the recording medium 103. The data describingthe structure of the recording medium 103 may be stored in the storagemedium 113 in association with its respective content item (e.g.,content item 113A-113B). The data describing the structure of thecontent item (“content item structure data”) may include a map relatingto content item features (e.g., preview, menu, and so on) to locationswithin the content item.

Using the content item structure information, the media player 101 mayallow the user 122 to skip to any portion or segment of a content item.For example, the user 122 may direct the media player 101 (e.g., via auser interface presented by the user interface component 104) toimmediately begin playing a particular chapter of an archived DVD movie,skipping the previews, menu, and the like.

The content item structure data may further include one or moreuser-defined bookmarks. The user-defined bookmarks may point toarbitrary positions within a content item. For example, the user 122(through the user interface component 104) may cause the media player101 to create a bookmark to a particular portion of an archived DVDmovie. This may allow the user to return to the bookmark withoutnavigating through the DVD chapter menu or the like. The content itemstructure information, including any user-defined bookmarks, may bestored as content item metadata (e.g., metadata 114A and 114B) withinthe storage medium 112.

The media analysis component 107 may also be used to detect and/or avoidmedia obfuscation schemes. The recording medium 103 may includeobfuscated data. Such obfuscation data may include one or more “badsectors” on the recording medium 103, which may cause a sequentialarchival of the recording medium 103 to fail. For instance, theobfuscation sectors may be linked together in an infinite loop and/orthe sectors may be configured to intentionally cause read failuresand/or timeouts. Successive timeouts and/or read failures due to the badsectors may cause an archiving process to fail and/or take an inordinateamount of time (in the case of an infinite loop, the archival may nevercomplete).

The media analysis component 107 may be used to analyze the recordingmedium 103 (e.g., “walk” the recording medium 103) to determine thevalid portions thereof. The media analysis component 107 may executevirtual machine instructions to allow the media analysis component 107to emulate the operation of a standard media player (e.g., a normal DVDplayer). During a walk operation, the media analysis component 107 mayaccess the recording medium 103 from its beginning (e.g., at the“first-play” program chain). The walk may follow the program chain as astandard media player would until a branch or other terminator isreached. In some cases, the media data read from the recording mediumduring the walk process may be discarded as quickly as possible. Thismay allow the media analysis component 107 to quickly walk the recordingmedium 103. Alternatively, the media analysis component 107 may read themedia data from the recording medium 103 for archival by the archivalcomponent 105.

When the walk process reaches a branching point (e.g., menu), the mediaanalysis component 107 may store a record of both its current state andthe state after following each branch (e.g., each menu option). Thecurrent state and branch state may be stored in a media walk datastructure (e.g., a stack), which may be used to determine which portionsof the recording medium 103 have been visited by the walk process. Abranch may be implemented as DVD instructions interpretable by thevirtual machine emulator of the media analysis component 107. The mediaanalysis component 107 may follow each branch to thereby determinewhether the branch represents valid data.

Alternatively, or in addition, before following a branch and/or addingthe branch state to a media walk data structure, the media analysiscomponent 107 may determine whether the branch is likely to lead tovalid data. For example, if a branch is reachable by an “invalid” menuoption, the portion of the recording medium 103 corresponding to thebranch (and data on the recording medium 103 associated therewith) maybe marked as “bad” and ignored. The media analysis component 107 maydetect invalid menu options in a number of different ways. For example,a menu option that falls outside of the viewable area of a display, is“invisible,” is very small, is displayed for only a few frames, or thelike, the media analysis component 107 may be considered an invalid menuoption. However, other invalid menu item detection techniques could beused according to the nature of the obfuscation scheme in use on therecording medium 103.

The current state of the media walker and the state of the walker afterfollowing any of the links may be stored in a media walker datastructure (e.g., on a stack-type data structure). The media analysiscomponent 107 may walk each branch of the recording medium 103 in thedata structure as described above. Subsequent branches may be similarlyevaluated and/or followed as described above. Upon reaching the end of abranch segment, the media analysis component may recursively traverseany remaining branches in the media walker data structure. If a branchleads to bad sectors, is circular (links back to an area of the discalready visited by the walk process), is an infinite still frame, isunreachable by other portions of the DVD, or the like, the branch (andportions on the recording medium 103 associated therewith) may be markedas “bad.” The branch evaluation and walking process may continue untilall valid sectors on the recording medium 103 have been identified(e.g., until all branches on the recording medium 103 have beenevaluated and/or walked). The result of the walk operation may be agraph data structure of the recording medium 103 comprising the validbranches and/or sectors thereon.

The walk process of the media analysis component 107 may be performedconcurrently with archival and/or playback of the recording medium 103.As such, the media analysis component 107 may communicate with thearchival component 105 and/or playback component 106 to synchronize thewalk operation such that the portions of the recording medium 103 readby the media analysis component 107 correspond to the portions requestedby the archival and/or playback components 107 and 108. Similarly, theoperation of the components 104, 107, and 108 may be synchronized tominimize disc seeking. In this way, the media analysis component 107 mayanalyze the structure of the recording medium 103 without disruptingarchival and/or playback of the recording medium 103.

The storage medium 112 may have sufficient storage space to hold aparticular amount of media content (e.g., a particular number of DVDmovies or the like). For example, the storage medium 112 may havesufficient storage capacity to allow for the storage of twenty (20) toone hundred (100) movies. In some embodiments, however, the storagemedium 112 may be expandable with additional internal and/or externalstorage to allow the media player 101 to hold an arbitrary amount ofmedia content.

In some embodiments, the media storage capacity of the storage medium112 may be increased by compressing the media content stored thereon.Video and/or audio content items on the recording medium 103 may beencoded in a first encoding format. For example, DVD movies on a DVDdisc recording medium 103 may be encoded in the Motion Picture ExpertsGroup 2 (MPEG-2) format. In addition, the DVD movie content may beencrypted (e.g., scrambled) using an encryption scheme, such as ContentScramble System (CSS), Data Encryption Standard (DES), Blowfish, or thelike. The encryption may serve a digital rights management (DRM)function to prevent unauthorized replication and/or playback of thecontent on the recording medium 103.

In one embodiment, the media player 101 is configured to re-encodecontent read from the recording medium 103 as it is archived on thestorage medium 112. For example, content originally encoded in theMPEG-2 format may be transcoded into a second (different) format, suchas H.264, VC-1, RealVideo®, or the like. The transcoding may beperformed in real-time or at such times as the media player 101 is notperforming other tasks. Similarly, the media player 101 may beconfigured to decrypt (e.g., unscramble) content on the recording medium103. The decrypted and/or transcoded content may be stored on thestorage medium 112 and/or made available for display (e.g., on thedisplay 120 and/or the remote display 124).

As described above, the decryption and/or transcoding operations of thetranscoder may be implemented using a general purpose processor, specialpurpose processor, and/or one or more special purpose hardwarecomponents.

The transcoder 108 may be configured to re-encode content items (e.g.,content items 112A and/or 112B) according to various different encodingformats. Alternatively, or in addition, the transcoder 108 may beconfigured to automatically transcode content read from the recordingmedium 103 as it is read by the media reader 102.

As an example, the storage medium 112 of FIG. 1 includes content items113A and 113B, each of which may have been encoded using MPEG-2, arelatively inefficient encoding format. In one embodiment, the contentitems 113A and 113B may be re-encoded using H.264, which producessubstantially smaller files while preserving the same quality. As aresult, the storage medium 112 may hold additional content items.Similarly, the recording medium 103 may include content encoded in theMPEG-2 format. As the archival component 105 stores the media content inthe storage medium 112, the transcoder 108 may automatically transcodethe media (e.g., into H.264, or another encoding format).

In addition to improving storage utilization, content may be transcodedfrom formats for which direct hardware decoding is not readilyavailable. For instance, the decoder 109 of the media player 101 may beconfigured to decode one or more media encoding formats. As discussedabove, the decoder 109 may include computer-readable instructionsexecutable by a general or special purpose processor and/or may compriseone or more hardware components.

However, the recording medium 103 and/or content items stored on thestorage medium 112 may be encoded in a format that is not supported bythe decoder 109, such as content encoded using Microsoft's Windows MediaVideo (WMV) encoding format. As such, in order to play back the content,the media player 101 may have to decode the WMV content using a softwaredecoding process (e.g., on a general purpose processor (not shown)),which may be computationally expensive and, in some cases, may producesub-par results. Accordingly, the transcoder 108 may be configured totranscode the content into a format that is decodable by the decoder109. This may allow the media player 101 to leverage the software and/orhardware decoding resources available on the media player 101 to providefor efficient, high-performance content playback.

Similarly, in some embodiments, the media player 101 may be configuredto transmit media content to a remote display, such as the remotedisplay 124. The remote display 124 may be communicatively coupled tothe media player 101 via a network 130. The network 130 may include anycommunications network known in the art including, but not limited to aTransmission Control/Internet Protocol (TC/IP) network, a wirelessnetwork (e.g., IEEE 802.1a-n network, Bluetooth®, or the like), acellular network (e.g., a 3G network or the like), a Local Area Network(LAN), a Wide Area Network (WAN), the Internet, or the like. The mediaplayer 101 may include a communications module 111 which may beconfigured to communicatively couple the media player 101 to the network130. Accordingly, the communications module 111 may include one or morecommunications interfaces, such as an Ethernet® communicationsinterface, a wireless network interface, a Bluetooth® interface, acellular telephone interface, a Public Switched Telephone Network (PSTN)interface, or the like.

The transmission of content from the media player 101 to the remotedisplay 124 may include streaming the content to the remote display 124over the network 130. The transcoder 108 may be configured to transcodemedia content read from the recording medium 103 and/or stored in thestorage medium 112 into a format suitable for transmission to and/ordisplay on the remote display 124. For example, video content encodedusing MPEG-2 may be transcoded into a RealVideo® stream, which may beefficiently transmitted to the remote display 124 via the network 130.The nature of the transcoding may depend upon the bandwidth available tothe media player 101 and the remote display 124 and/or the capabilitiesof the remote display 124. For instance, the remote display may includeone or more decoders capable of decoding media content in a particularencoding format. The media player 101 may be configured to determinewhich formats are supported and/or preferred by the remote display 124and to transcode the media content transmitted to the remote display 124accordingly.

As discussed above, the transcoder 108 may transcode media content as itis read from the recording medium 103 and/or after archiving the mediacontent on the storage medium 112. The transcoder 108 may transcode codemedia content for various purposes including, but not limited todecrypting (e.g., unscrambling) the media content, compressing the mediacontent (e.g., to increase the virtual storage capacity of the storagemedium 112), transcoding the content into a format for which hardwaredecoding is available (e.g., into a format adapted for the decoder 109),transcoding the media content into a streamable format, transcoding themedia content into a format suitable for display on a remote displaydevice, such as the remote display 124, or the like.

As discussed above, the user interface component 104 of the media player101 may allow the user 122 to control the operation of the media player101. Control instructions may be received via a remote control device104 and/or via one or more interfaces on the media player 101 (e.g.,controls disposed on the player 101, such as buttons, toggles, and thelike) and/or controls presented on the display 120. For instance, thedisplay 120 may be a touch screen display. The media player 101 maycause one or more control interfaces to be presented on the display 120to allow the user 122 to control the operation of the media player 101.

The user interface component 104 may provide a “play and save” input.Selection of the “play and save” input may cause the media player 101 toarchive the media content on the recording medium 103 while playing backthe media content on the display 120 and/or remote display 124. As such,the recording medium 103 may be concurrently archived and played byinvoking a single command. Alternatively, or in addition, the mediaplayer 101 may be configured to begin archiving the recording medium 103upon detecting insertion of the recording medium 103 into the mediareader 102.

As discussed above, the media player 101 may be configured to displaymedia content stored on the recording medium 103 while concurrentlystoring the media content in the storage medium 112. In this way, anarchive or library of stored content items (e.g., content items113A-113B) may be created while the user 122 views the content.Accordingly, the user 122 need not archive the media content in aseparate step (e.g., the user 122 need not separately archive and viewthe content items 113A-113B since the content items 113A-113B are storedas the user views the respective content items). Similarly, a user 122may archive the media content on a recording medium 103, while playingback archived media content (e.g., content items 113A or 113B).

The media reader 102 may be capable of reading the recording medium 103faster than the normal playback speed. For instance, the recordingmedium reader 102 may be capable of reading data from the recordingmedium 103 at 4× to 16×, i.e., four (4) or sixteen (16) times playbackspeed. Accordingly, the media player 101 may be capable of archiving themedia content on the recording medium 103 before the user 122 isfinished viewing the content item. In such an embodiment, the playbackcomponent 107 may be configured to play media content read from thestorage medium 112 rather than from the recording medium 103 directly.

The user interface component 104 of the media player 101 may includecontrols to allow the user 122 to control the playback of the mediacontent. For example, as the media player 101 concurrently plays backand archives media content on a recording medium 103, the user 122 mayinstruct the player 101 to navigate to a different location within thecontent (e.g., fast forward within the content, jump a particularchapter or section, or the like).

These instructions may be received before all of the media content hasbeen archived on the storage medium 122. When the media player 101receives such a navigation instruction, the player 101 may determinewhether the requested content has been stored on the storage medium 122.If the media content is not yet available on the storage medium 122, thearchival component 105 may “skip” to the requested location and tocontinue archiving the media. This may allow the playback component 106to play the media at the requested location (e.g., by reading therequested location within the media content from the storage medium112). If the requested media content has already been archived, theplayback component 106 may obtain the requested content from the storagemedium 112 and display the content for the user 122.

To track which portions of the media content on the recording medium 103have been archived (e.g., stored on the storage medium 112), thearchival component 105 may maintain a data allocation map (DAM)associated with the media content on the recording medium 103. In someembodiments, the DAM may include a table-like data structure comprisinga list of sectors on the recording medium (or other delimiters, such ascells, nodes, or the like) with respective, corresponding indications astatus of the portion of the recording medium. The status may indicatewhether the portion of the recording medium 103 has not yet beenaccessed; whether the portion of the recording medium 103 has beenarchived (e.g., stored in the storage medium 112); whether a read errorand/or timeout was encountered when the portion of the recording medium103 was accessed (e.g., the portion of the recording medium 103 may bedamaged); whether the portion of the recording medium 103 containsinvalid data; and the like. As various sectors of the media content areaccessed and stored in the storage medium 112, the archival component105 may update the DAM to indicate that the sectors have been archivedand are available for playback from storage medium 112.

Using the DAM, the playback component 106 may determine whether aparticular portion (e.g., sector) of the media content of the recordingmedium 103 is available on the storage medium 112. Similarly, the DAMmay be used by the archival component 105 to “fill in” any missing(e.g., un-archived) sectors of the media content item on the storagemedium 112. For example, a user may insert a DVD recording medium 103into the media player 101 and immediately navigate to an ending portionof the media content (e.g., a last chapter of the DVD movie). Similarly,a user may insert a DVD, play a portion of the DVD, and then eject itbefore the archival component 105 finishes archiving the media contentthereon. As described above, during navigation and/or reinsertion of therecording medium 103, the media player 101 may access the DAM associatedwith the recording medium 103 to determine whether the requested portionhas been archived. If not, the media player 101 may direct the archivalcomponent 105 to navigate to the requested portion of the recordingmedium 103, and the content may be archived and made available forplayback as described above. The archival of the requested portion ofthe content may allow the playback component 106 to play the mediacontent from the storage medium 112. After the media player 101 hasarchived the requested portion of the recording medium (e.g., the “end”of the media content), the archival component 105 may be configured togo back and archive any skipped portions of the content. The skipped(un-archived) portions of the content item may be identified using theDAM. Similarly, if the DAM indicates that read errors were encounteredduring archival, the archival component 105 may attempt to re-archivethose portions of the recording medium 103.

The metadata component 110 of the media player 101 may be configured toreceive and associate one or more pieces of data (e.g., metadata) withcontent items stored in the storage medium 112. The metadata may includedescriptive information associated with a respective content item (e.g.,metadata 114A may describe the content item 113A, and the metadata 114Bmay describe the content item 113B). The metadata may include one ormore metadata items relating to a content item (e.g., DVD movie, audiotrack, or the like) and may include, but are not limited to, a title ofa content item, a table of contents, a rating, a credits listing, a plotsynopsis, one or more graphical assets (e.g., an image of a DVD moviecover, image(s) associated with a scene (which may comprise a referenceto such image(s) within the content item), or similar), one or moretags, one or more content item categories, a content item genre, and soon.

The metadata component 110 may receive metadata associated with acontent item (e.g., metadata 113A an 113B) from the user 122 via theuser interface component 104 (e.g., the user 122 may manually inputmetadata describing the content). Alternatively, or in addition, themedia player 101 may be configured to obtain metadata relating to acontent item from a metadata provider 132 accessible via the network130. The metadata component 110 may be communicatively coupled to themetadata provider 132 via the network 130. In some embodiments, themetadata provider 132 may include and/or be communicatively coupled to ametadata data store 133. The metadata data store 133 may includemetadata relating to a plurality of different content items (e.g., DVDmovies or the like). Alternatively, or in addition, the media player 101may include a local metadata data store (not shown) similar to the datastore 133, which may include metadata relating to various content item(e.g., DVD movies, music albums, or the like). The local metadata storemay be pre-loaded with metadata relating to various content items (e.g.,metadata of hundreds or thousands of DVDs, CD, and so on). The localmetadata data store may be periodically updated via the network 130,updated via the media reader 122 (e.g., a recording medium 103 mayinclude additional metadata), updated by a removable storage medium, orthe like.

To receive metadata information relating to a content item from themetadata provider, the metadata component 101 may generate and transmitmetadata query to the metadata provider 132. The query may identify thecontent item for which metadata is requested. The content itemidentifier may include, but is not limited to a title of the content, atable of contents, a DVD media identifier, a value derived from one ormore identifiers (e.g., a hash value or the like), a combination ofidentifiers, or other identifying information. The content itemidentifier may be transmitted to the metadata provider 132 (e.g., in aquery for metadata), and may be used by the metadata provider 132 tolook up metadata related to the content item in the metadata data store133. Upon accessing the metadata information, the metadata provider 132may transmit the information to the metadata component 110 via thenetwork 130.

The metadata component 110 may be configured to store the metadatareceived from the metadata provider 132 in the storage medium 112. Themetadata may be associated with (e.g., linked to) a respective contentitem in the storage medium 112 (e.g., the metadata 114A may beassociated with content item 113A, and metadata 114B may be associatedwith content item 113B). The association may be made by a databaseassociation (e.g., as a table within a database, as a key value, or thelike), a data structure association (e.g., within an XML or otherstructured data format), or the like.

The user interface component 104 may display metadata associated withone or more a content items. For example, the user interface component104 may display content items 113A-113B stored on the storage medium 112in a list or other selection interface. Each content item in the listmay be displayed in conjunction with one or more pieces of metadata. Forexample, a DVD movie content item 113A may be displayed using metadatacontent, such as a graphic of the DVD movie cover, the DVD movie title,a scene from the DVD movie, a DVD movie rating, a plot synopsis, agenre, one or more tags, or the like.

The user interface component 104 may include various different contentitem display interfaces. For example, the user interface component 104may include display interfaces that include only content items of aparticular genre (e.g., action), a particular rating, or the like. Themetadata of the content items 112A-112B stored may be used to determinewhether a particular content item should be included in the list.

The metadata 114A and 114B associated with the content items 113A and113B may allow for sorting and/or searching thereof. For example, a usermay search the content items 113A-113B for a particular actor name(e.g., “De Niro”). Responsive to the search, the user interfacecomponent 104 may cause a listing of content items having the term “DeNiro” in the list of actors to be presented on the display 120. Anysearch term pertaining to any metadata category and/or type could beused under the teachings of this disclosure.

FIG. 2A is a flow chart of one embodiment of a process 200 forconcurrently archiving and playing a content item. At step 210, theprocess 200 may be initialized by allocating and/or initializingrequired resources, such as memory, storage locations, networkconnections, device (e.g., a media reader device), and the like.

At step 220, a recording medium may be inserted in a media reader. Forinstance, the recording medium may include a DVD movie, and the mediareader may be a DVD media reader.

At step 230, the process 200 may instruct the reader to begin readingthe content from the DVD media at a media read rate. As discussed above,many media readers are capable of reading data at a higher rate thanplayback speed (e.g., 16× playback speed).

At step 240, media content read from the media reader may be archived ina storage medium.

At step 250, and concurrently with step 240, the media content archivedin the storage medium may be accessed and presented on a display. Since,as discussed above, the media reader may be capable of reading data fromthe media at or above playback speed, the playback of step 250 may occurconcurrently with the archiving of step 240.

At step 245, the storage of the content item in a storage medium maycomplete, and, at step 255, the playback of the content item maycomplete. As discussed above, since the media reader may be capable ofreading media at or above playback speed, the storage of the contentitem at step 245 may complete before the playback of the content item atstep 255.

As discussed above, after archiving the content item on the storagemedium, the content item may be made available for subsequent playback.The content item may be played back directly from the archived contentin the storage medium and, as such, may not require the recording medium(e.g., DVD disc) to be present in the media reader for playback.

FIG. 2B is a flow chart of another embodiment of a process 201 forconcurrently archiving and playing a content item. At step 211, theprocess 200 may be initialized as described above in conjunction withstep 210 of FIG. 2A. At step 221, an instruction to “play and save” acontent item stored on a recording medium may be received. Theinstruction may be received by means of a remote control device, one ormore inputs disposed on a surface of a media player, or the like. Theplay and save instruction may, in a single step, cause the process 201to concurrently archive and playback a content item stored on arecording medium. The concurrent archival and playback of steps 231-256may be performed as described above in conjunction with steps 230-255 ofFIG. 2A.

FIG. 3A is a flow chart of one embodiment of a process 300 forconcurrently storing and playing back a content item. At steps 310 and320, the process 300 may be initialized, and a recording medium may beinserted into a media reader as described above.

At step 325, a data allocation map (DAM) may be generated for thecontent on the recording medium. As described above, the DAM may includea map of the portions of data available on the media (e.g., arrangedinto sectors, chapters, nodes, or the delimiter types). Each of theportions on the media may be associated with an indicator showing thestatus of the respective portion. The DAM may support various differentindicators including, but not limited an indicator that the portion hasbeen archived (e.g., is stored on a storage medium); an indicator thatthe portion has been accessed for archiving (e.g., no attempt has yetbeen made to archive the portion of the recording medium); an indicatorthe last attempt to access the portion resulted in a read error ortimeout; an indicator that the portion of the recording medium comprisesinvalid data (e.g., as indicated by a media analysis component, such asthe component 107 of FIG. 1); and so on. For example, the indicator of aparticular portion may be a Boolean and/or bitwise indicator (e.g.,bitmask) to reflect one or more of the states discussed above (e.g., abitwise one (1) may indicate that the portion has been archived, abitwise zero (0) may indicate that the portion has not been accessed, atwo (2) may indicate an error was encountered, and so on).

At steps 330, 340, and 350, the process 300 may direct the media readerto begin reading media content from the media, to archive the mediacontent in a storage medium, and to playback the stored media content asdescribed above.

The archiving of step 340 may take place over time. For example, themedia reader may sequentially read portions of the content item from therecording medium. As each portion (e.g., sector, segment, or otherdelimiter) of the content item on the recording medium is read, it isarchived at step 340. If a portion of the recording medium issuccessfully archived, the DAM may be updated accordingly. If a readingerror and/or timeout is encountered, the process 300 may re-try readingthe portion a threshold number of times. The read attempt threshold maybe adaptable according to the progress of the playback portion of theprocess 300 (e.g., at steps 350-353 below). For example, if the playbackprocess is occurring in the logical vicinity of the portion, the numberof read attempts may be reduced to prevent the attempts from interferingwith the playback. Alternatively, if the playback process is not playingback media content in the logical vicinity of the portion, the number ofread attempts may be increased since the read attempts are unlikely tointerfere with playback.

The archiving of step 340 may be performed in conjunction with a mediaanalysis component, such as the media analysis component 107 of FIG. 1.As discussed above, the media analysis component may walk the recordingmedium to determine which portions of the recording medium contain validmedia data, and which do not. This information may be stored in a graph,a list, or other datastructure describing the structure of the recordingmedium. As such, at step 340, the process 300 may use the informationgathered by the media analysis component to avoid portions of therecording medium that have been marked as containing “invalid data”(e.g., may consult the graph, list, or other data structure beforeidentifying the valid and invalid portions of the recording mediumbefore attempting to archive a portion of the recording medium).Similarly, in other embodiments, at 340 the process 300 may restrict thearchiving to only the portions of the recording medium identified by themedia analysis component as containing valid media content.

At step 341, the DAM may be updated to reflect the status of the portionof the recording medium. For example, if the portion of the recordingmedium was successfully archived, the corresponding entry in the DAM maybe updated to indicate that the portion is available on the storagemedium. If a read error and/or time out was encountered, the DAM may beupdated to indicate the error. In some embodiments, the error indicatormay indicate the number of attempts made to read the content. Similarly,the DAM may be updated to indicate that a media analysis componentdetermined that the portion contains invalid data.

At step 351, the process 300 may receive an instruction to navigate toanother portion of the content item on the recording medium. Forexample, the process 300 may receive an instruction to navigate to aparticular chapter within a DVD movie. The navigation instruction ofstep 351 may be received from a user of the process 300 via a userinterface (e.g., user interface 112 of FIG. 1).

At step 353, the process 300 may determine whether the portion of themedia content item requested at step 351 has been archived and isavailable for playback from the storage medium. The determining of step353 may include accessing the DAM associated with the content item. Ifthe DAM indicates that the portion could not be archived due to a readerror and/or timeout, the portion may be skipped by the playback, and a“next” navigation may be directed to the next “good” portion of therecording medium. The “next” portion may be the following segment of therecording medium and/or a portion linked to the segment in the recordingmedium. This skipping may cause the playback to jump around the damagedportion of the recording medium. If the requested portion (or next goodportion) of the recording medium is available, the flow may continue atstep 350 where the process 300 may play the requested portion of thecontent item from the storage medium. If the requested portion is notavailable, the flow may continue at step 360.

At step 360, the process 300 may instruct the media reader to access therequested portion of the content item. This may cause the media readerto “skip” to another portion of the recording medium. After navigatingto the requested portion of the recording medium, the process 300 mayread the content item from the requested position at step 330. Therequested portion will be archived at step 340, and the DAM will beupdated at step 341. As such, the requested portion of the content itemmay be played back from the storage medium at step 350 as describedabove.

At step 345, the media reader may reach an “end” of the content item. Atstep 347, the DAM may be evaluated to determine whether all of thecontent item has been archived on the storage medium. As describedabove, the content item may not be stored sequentially due to usernavigation within the content item. As such, the DAM may have one ormore gaps. At step 347, the DAM may be accessed to determine whether anyportion of the content item has not been archived (e.g., whether any ofthe entries in the DAM are “FALSE” or zero (0)). If no such portionsremain, the content item has been completely archived, and the flow mayterminate at step 380.

At step 370, if portions remain to be archived, the process 300 mayinstruct the media reader to access the un-archived portions of thecontent item on the recording medium. The missing portions of therecording medium may then be archived in the storage medium at steps 340and 341, as described above. Since the process 300 plays back thecontent item from the storage medium, the navigation and archival ofsteps 370, 340, and 341 may be performed concurrently with playback ofthe content item without interfering with the playback of the contentitem.

FIG. 3B is a flow chart of another embodiment of a process 310 forarchiving and playing back media content from a recording medium. Atstep 311, the process 301 may be initialized as described above.

At step 321, a command to play and archive media content on a recordingmedium may be received. The command of step 321 may be received via auser interface component (e.g., via a user interface input produced bythe user interface component 104 of FIG. 1). Alternatively, or inaddition, the command of step 321 may be produced responsive todetecting insertion of a recording medium into a media reader (e.g.,detecting the insertion of a DVD disc into a DVD reader of a mediaplayer).

At step 323, the process 301 may determine whether a DAM exists for therecording medium in the media reader. In some embodiments, this maycomprise generating a recording medium identifier or media contentidentifier. Examples of various recording medium and/or media contentidentifiers are provided below in conjunction with FIG. 4. Upongenerating the identifier, the process 301 may determine whether a DAMhas been associated with the identifier, by querying a storage mediumfor the DAM using the identifier (e.g., the storage medium 112 of FIG.1). For example, the storage medium may include a relational database orother data relational system (e.g., search functionality provided by thestorage medium). DAM data structured stored on the storage medium may beassociated with the identifier (e.g., as a “key” of a database table ofthe DAM or the like). If a DAM for the recording medium exists, the flowmay continue at step 329; otherwise, the flow may continue at step 326.

At step 326, a new DAM may be generated for the recording medium asdescribed above. The DAM may be keyed to a recording medium identifierand stored in a storage medium for subsequent access by the process 301.

At step 329, the existing DAM for the recording medium may be accessed.The existing DAM may indicate that portions of the recording medium havealready been archived in the storage medium. As such, the process 301may not need to re-archive the entire recording medium, rather onlythose portions of the recording medium which, as indicated by the DAM,have not yet been archived. Similarly, playback of the archived portionsof the recording medium may be possible without re-archiving. Inaddition, the existing DAM may include media analysis information (e.g.,a graph or other structure generated by the media analysis component 107of FIG. 1). The media analysis information may indicate which portionsof the recording medium are valid, which contain errors (e.g.,scratches), and so on.

At step 342, the process 301 may read content from the recording medium,archive the content in a storage medium, and update the DAM as describedabove. Also as described above, at step 352, media content may be playedback from the storage medium. Although not depicted in FIG. 3B, thereading and archiving of step 342 may navigate to different portions ofthe recording medium responsive to the playback. For example, a user mayrequest playback of a portion of the recording medium that has not yetbeen archived. Responsive to such a command, the recording medium may beread and archived at step 342 at the requested location as describedabove.

At step 361, a command to stop the play and archive process may bereceived. The command of step 361 may be received via a user interfaceinput. Alternatively, or in addition, the command may be producedresponsive to the recording medium being ejected from the media reader.

The command of step 361 may be received before the recording medium hasbeen fully archived (e.g., before all of the media content on therecording medium has been stored on the storage medium). However, thepartial archive (and DAM associated therewith) may be maintained on thestorage medium. Upon subsequent insertion of the recording medium (orcommand to play and/or archive the recording medium), the process 301may pick up where it left off. In some embodiments, the partial archivemay be maintained on the storage medium indefinitely. Alternatively, thepartial archive may be maintained for a threshold period of time or maybe maintained as long as there is sufficient storage space within thestorage medium (e.g., after a threshold period of time and/or upondetecting that the storage medium is running low on storage space, thepartial archive may be removed). Similarly, a user interface option mayallow a user to decide whether and/or how long the partial archiveshould be maintained. If sufficient media content has been stored,playback of the partially archived media content may be provided asdescribed above.

After receiving the command of step 361, the process 301 may return tostep 321 where a command to archive the recording medium may bereceived. As discussed above, the command of step 321 may be receivedresponsive to detecting insertion (or re-insertion) of the recordingmedium into the media reader). Similarly, the command of 321 may bereceived via a user interface component. As shown in FIG. 3B, afterreceiving the command of step 321, the process 301 may continue thearchival of the recording medium where the process 301 left off; the DAMmay be detected and accessed at steps 323 and 329. Using the DAM, theprocess 301 may determine which of the recording medium remain to thearchived. In this way, the process 301 may not have to re-archiveportions of the recording medium that have already been stored, attemptto archive portions of the recording medium that contain invalid data(e.g., as indicated by a graph or other structured generated by a mediaanalysis component), and so on.

As discussed above, in some embodiments, the DAM indicator of aparticular portion of the recording medium may include a plurality ofindictors including, but not limited to an “archived” indicator toindicate that the portion has been stored on the storage medium; anun-archived indicator to indicate that the portion has not yet beenstored on the storage medium; an indicator that the portion of thestorage medium contains invalid data; and/or an “error” indicator toindicate that a read error was encountered during archiving.

In some embodiments, at step 342, the process 301 may ignore portions ofthe recording having an “error” indicator in the DAM. This may speed upthe archiving by preventing attempts at archiving portions of therecording medium thought to be damaged. Alternatively, the process 301may attempt to archive portions of the recording medium marked with an“error” indicator. This may give the process 301 another attempt atarchiving the portion. For example, after stopping the playback andarchival process 301 at step 361 (e.g., by ejecting the recording mediumand/or receiving a command via a user interface), a user may haveattempted to repair the recording medium and/or may have procured adifferent copy of the recording medium. As such, the portion of therecording medium that caused an error during a previous read attempt,may be successfully read in a subsequent attempt.

In an alternative embodiment, the media player 101 may access apre-existing DAM, provided by a metadata provider 132 or other party whomay aggregate DAM information, and may use the pre-existing DAM to speedup archival or the recording medium 103 and/or to compare the data onthe recording medium 103 to that in the pre-existing DAM. In anotherembodiment, the media player 101 may transmit the locally generated DAMto a metadata provider 132 or other party who may aggregate DAMinformation. FIG. 4 is a flow chart of one embodiment of a process 400for acquiring metadata relating to a content item. At step 410, theprocess 400 may be initialized as described above.

At step 420, a content item may be archived. The archiving of step 420may be performed using, for instance, the system 100 of FIG. 1 and/orusing a process or processes, such as the processes 200, 201, and/or 300described above.

At step 430, a content item identifier may be generated. The contentitem identifier may be a title of the content item, a recording mediumidentifier, a table of contents of the content item, a partial orcomplete DAM, a hash value comprising a combination of identifiers, orthe like. The identifier may be generated before completion of thearchival of the content item. For example, the content item identifiermay be generated (and the metadata may be retrieved) upon detectinginsertion of the recording media.

At step 440, a request for metadata may be generated and submitted to ametadata provider. The request submitted at step 440 may include thecontent item identifier generated at step 430. Submitting the requestmay comprise transmitting the request to a metadata provider over anetwork. As described above, a metadata provider may receive therequest, and, using the content item identifier generated at step 430,may access (e.g., look up) metadata related to the content item in acontent item database or other data store.

The metadata provider may transmit a response to the request of step430. The response may include metadata relating to the content item. Theresponse may be received at step 450. At step 460, the metadata may bestored in a storage medium (e.g., in the storage medium 112 of FIG. 1).The metadata may be associated with the content item in the storagemedium (e.g., via a database association, a structural association, orthe like).

The metadata associated with the content item may be used to categorizethe content item according to a content item genre, rating, or the like.Similarly, the metadata may be searchable. This may allow a user toperform detailed searches for particular types of content items. Forexample, a user may search for all content items in the “action” genre,having a “PG-13” rating or lower, and so on. Similarly, the metadata maybe used in content item listings or other display interfaces. Forexample, a set (e.g., list) of content items may be presented bydisplaying metadata associated with each content item in the set. Forinstance, a set of DVD movie content items may be presented bydisplaying graphical metadata (e.g., DVD movie cover) and title metadataof the respective content items.

FIG. 5A is a flow chart of one embodiment of a process 500 forconcurrently archiving and playing a content item.

At steps 510, 520, and 530, the process 500 may be initialized (step510), media may be inserted into a media reader or a play and savecommand may be received (step 520), and media content may be readtherefrom (step 530) as described above.

At step 531, the process 500 may determine whether the media contentshould be transcoded from a first format (e.g., “native format”) inwhich the content is encoded on the recording media to a second formatfor archival on the storage medium and/or playback. The process 500 maytranscode the media content for various reasons. For example, thecontent item may be transcoded into a compressed format to reduce thesize of the content item on the storage medium. Alternatively,transcoding may be performed into an encoding format adapted for usewith dedicated media decoding hardware and/or optimized decodingsoftware. Similarly, the process 500 may be configured to transmit mediacontent to a remote device for display (e.g., to stream the content to aremote display device over a network, such as the Internet). As such,the second format may be a streaming video format and/or a formatadapted for use by the remote display (e.g., a codec that the remotedisplay device is capable of rendering, such as RealVideo® or the like).If, at step 531, the process 500 determines that the media content is tobe transcoded, the flow may continue at step 533; otherwise, the flowmay continue at step 540 and 550.

At step 533, the media content may be transcoded into a second format.The transcoded media content may be stored in the storage medium and/orplayed back at step 540-555 as described above.

FIG. 5B is a flow chart of another process for transcoding media contenton a storage medium. In the FIG. 5B example, the transcoding may notoccur in real-time (e.g., as the media content is archived and/or playedback). Rather, the transcoding may occur while the media player (orother device on which the process 501 is implemented) is idle. As such,the transcoding (which may take place in software and, as such, requiresignificant processing resources) may not interfere with the normaloperation of the media player.

At steps 511, 521, and 532, the process 501 may initialize (step 511),detect insertion of a recording medium and/or receive a play and savecommand (step 521), and read media content from the recording media(step 532) as described above.

At step 533, the process 501 may determine whether the media contentread from the recording medium should be transcoded from a first format(e.g., native format) into a second encoding format. As discussed above,transcoding may be done for various reasons, such as to reduce the sizeof the content item on the storage medium, to encode the content into anencoding format compatible with decoder hardware and/or software, toadapt the content for transmission over a network, and the like. If atstep 533, the process 501 determines that transcoding should occur, theflow may continue at step 535; otherwise, the flow may continue at steps541 and 551.

In some embodiments, transcoding the media content may not be done atreal-time speed, particularly if the transcoding involves transcodingbetween encoding formats for which the process 501 does not havededicated hardware (e.g., the transcoding must be done in software). Assuch, at step 535, the transcoding may not occur in real-time (e.g., asthe media content is archived and/or played back to a user). Rather, atstep 535, the media content stored on the storage medium may be markedfor transcoding at a later time. The marking may comprise storing anindicator (or other data) with the media content on the storage media.The indicator may indicate that the media content should be transcodedwhen possible and may further indicate the encoding format to which thecontent should be transcoded (e.g., may indicate the desired encodingformat for the media content). This may allow the process 501 totranscode the media content at a later time (e.g., when the process 501is idle).

At steps 541-556, the media content may be archived and/or played backas described above.

At step 561, after the archiving and/or playback has completed, theprocess 561 may determine whether the media content is marked fortranscoding and whether media player (e.g., or other device on which theprocess 501 is implemented) has sufficient computing resources totranscode the media content. If processing resources are available (andthe content item is marked for transcoding), the flow may continue atstep 563; otherwise, the flow may continue at step 561 where the process501 may continue waiting for an idle condition.

At step 563, the process 501 may transcode the media content item fromthe first encoding format to a second encoding format. Although notshown in FIG. 5B, the process 501 may monitor the state the media player(or other device on which the process 501 is performed) to determinewhether the processing resources used to transcode the media content areneeded (e.g., to archive additional recording media, to playback mediacontent, and so on). If the resources are needed, the transcoding ofstep 563 may be suspended, and the flow may continue at step 561 toresume transcoding the content when the processing resources becomeavailable.

Although FIGS. 5A and 5B do not depict the creation of a DAM and/or usernavigation within the content item and/or interruption thereof (e.g., asshown in FIGS. 3A and 3B), one skilled in the art would recognize thatthe transcoding depicted in FIGS. 5A and 5B could be applied to theprocesses of FIGS. 3A and 3B and vice versa.

FIG. 6 is a flow chart of a process 600 for concurrently storing andplaying media content. At steps 610, 620, and 630 the process 600 may beinitialized (step 610), detect insertion of media into a media reader orreceive a play and save command (step 620), and read media contenttherefrom (at step 630) as described above.

At step 631, the process 600 may determine whether the media contentshould be transcoded for storage. As discussed above, there are variousreasons media content item may be transcoded including, but not limitedto compressing the media content, adapting the media content forplayback by specialized hardware and/or software, transcoding the mediacontent into a scalable media format (e.g., an encoding formatcontaining layers which may be combined to improve fidelity), and thelike. If the process 600 determines that the content item should betranscoded for storage, the flow may continue to step 633; otherwise,the flow may continue to steps 640 and 635.

At step 633, the media content may be transcoded for storage. At steps640 and 645, the media content may be stored in the storage medium asdescribed above.

As described above, the media content may be played back concurrentlywith the storage and/or transcoding of the media content. In some cases,the encoding (e.g., format) used to store the media content may not beoptimized for playback. For example, the media content may be playedback on a remote display communicatively coupled to the process 600 viaa network. The remote display may require that the media content betranscoded into format capable of being transmitted to and/or displayedby the remote client (e.g., a streaming format, such as RealVideo® orthe like). However, due to bandwidth considerations, the streamingformat may be a relatively low bitrate (and hence of relatively lowfidelity). As such, the media content may not be stored in a streamingformat. Similarly, the playback device may include specialized decodinghardware and/or software. The media content may be transcoded tooptimize playback using the identified hardware and/or software.

Moreover, the media content may be stored on the storage medium in ascrambled (e.g., encrypted) format for security purposes, in acompressed format, or the like. As such, at step 635, the process 600may determine whether the format in which the media content is stored iscompatible with the desired playback of the content. If transcoding forplayback is desired, the flow may continue at step 637; otherwise, theflow may continue at step 650.

At step 637, the content may be transcoded into a third format. At step650, the media content (either transcoded or as read from the storagemedium) may be played back. The playback of step 650 may includedecoding the media content and causing the media content to be displayedand/or presented to a user. Alternatively, or in addition, the playbackmay include streaming the content to a remote user over a network, suchas the Internet. In this case, the decoding and presentation of themedia content may take place on a remote device (e.g., a terminal,computer system, or the like). At step 655, the playback of the contentitem may be completed as discussed above.

Although FIG. 6 does not depict the creation of a DAM and/or usernavigation within the content item (e.g., as shown in FIG. 3), oneskilled in art would recognize that the transcoding depicted in FIG. 6could be applied to the process of FIG. 3 and vice versa.
